This research work investigated the different effects of concentrations of alkaline treated coconut shell (5, 10, 15 and 20%v) of particle sizes 200μm, 300μm and 500μm on mechanical and thermal properties of epoxy matrix composite. Mechanical properties investigated were strength and hardness. Differential Thermal Analysis (DTA) was adopted for analyzing the thermal behavior of the composite. The results showed that the hardness and strength increased correspondingly with increasing coconut shell (CS) particulates contents and decreased with increasing particle size. Average UTS of 40.6 MPa and hardness of 49 BHN were obtained at 20%V and 200µm particle size. The thermal analysis results showed average glass transition temperature (Tg) of 172.4°C and melting temperature (Tm) of 384.2°C which decreased to 165.5°C and 394.0°C respectively by increasing coconut shell content to 20%V.
